Google Classic VPN stopped working after an outage

  • 772

Please help!

My google cloud classic VPN to on prem network stopped working yesterday after a network outage.

The VPN is established on site on cisco asa but the pkt dcaps are 0. The tunnel is active.

The google log has warnings like this: "Warning: Local traffic selectors narrowed for Child SA: vpn_x.x.x.x. Configured TS: [0.0.0.0/0 ], negotiated TS:[10.210.3.8/32 10.210.0.0/16 ]. Please verify configuration on the remote side."

I have not changed any configuration on the asa or on gcp side. Can someone please help me on what might be going on here? I will really appreciate it.

Thanks, Ankit

    This very likely indicates that the Traffic Selectors are configured differently on two sides. Please unify the TS configuration for GCP VPN tunnel and on-prem and re-create the tunnel if necessary.
